The defendant conducted a "candy game" with the youngsters, the legal counsel explained, in which he would enter the boys' rooms when they were getting ready for bed and ask them to eat sweets "as quickly as they can".
She informed the proceedings Ruben had conducted this practice with the children "over an extended period", and youngsters had previously fallen ill the next day.
She stated the man had been successful in rationalizing this over a long period as the children being "overexcited from fun", until his family member had suspicions in recently.
Mrs Prior KC stated further: "In the summer" his family member had worries about what was going on, for good reason.
"They resolved" to examine in the individual's items."
Mrs Prior KC stated items including infant oil, petroleum jelly and injection devices were found, and his stepchild contacted the authorities about his worries.
She explained Ruben proceeded to engage in the "candy game" with six youngsters that night - Saturday 26 July - and they were all ill the subsequent day.
"Authorities" had not gone out by that stage," she continued.
The regulatory agency, the investigative body, previously told that it was investigating Leicestershire Police's handling of the incident.
Mrs Prior stated the youngsters were struggling to walk due to being ill, so Ruben's stepson contacted the police again.
